Registeel #SM75 from SM Black Star Promos is a reverse holo promo card that currently sells for about $23.50 ungraded, with graded copies ranging from $42.50 at grade 7 to $61.00 at grade 9.5. A grade 9.5 copy sells for around $61.00, about 2.6× the $23.50 raw price, so high-grade copies are worth grading.
